ments inSheet-Metal Windows, of which the I following is a specification.

'Ihis invention is an improved pivotal connection for sheet-metal wlndow-sashes which; swing to open the same.

The object of the lnvention is to'provide simple device of the kind having the particular characteristics that the pivot-bolt is set at the middle vertical line of the sash-stile and is concealed. An 4adjustment is also permitted to make the sash fit properly.

In the accompanying drawings, Figure 1 is an elevation of a portion of the stile of the window-sashprovided with my improvement.. Fig. 2 is a section on the line 2 2 of Fig. l.

Referring specifically to the drawings, 6 indicates the window-trame, and 7 the stile of the sash. 8 is a side stop which fits be-. tween the edge of the sash-stile and the casing. Its flanges are fitted and ixed in grooves 9 formed in the sash-frame. These parts are made Aof sheet metal andare accordingly hollow, asshown. The stile has a groove to receive the edge of the glass 9.

A pivot-bolt is indicated at 10. This bolt extends horizontally through the side stop' and into the stile, and its head is seated in a plate 11, fitting within the side stop. This 3 5 gives the necessary support and vbacking for the pivot-bolt. This bolt screws into an angular lug or block 12, which is located within the hollow stile and is clamped against one side thereof by screws 13, which extend through slots 14 in a plate 15 on the'outside ofthe stile. The screws clamp the plate and block together and give the necessary strength and solidity to support the sash as it swings on the pivots. Theslots 14 allow the sash to be raised or lowered to a limited extent to adjust 1t to its proper position in the frame.

On its inner edge the stile is groovedjto receive the metal Weather bar or strip 16. This extends len tliw'ise in the groove, and its outer curve surface fits in a shallow channel 17, formed-in the edge'of the sto 8. When the 4sash is swung on itspivots, t iis Weather strip or bar is forced 'bac into the recess by the wedge action of, the stop on f/he curved "surface of the strip.= IVhen'the sash is closed,

the strip is forced into position'by springs near its, ends in a known manner.

The iv'otal devices, vtion is directed, provide cheap and e `ective means for pivoting metal sash. The plates 11 and 15 and tin` angular block 12 can be chea ly castvto accommodate stock screws.

tpl which this a plicaat I claim as new, and'desire to secure by Letters Patent, is

l.. A sheet-metal window, havinga hollow stop on the trame thereof, a plate in the stop, a pivot-bolt projecting through Vthe plate and stop and into thesash-stile, tened in the stile, and into which the bolt extends.

2. A sheet metal Window sash having 'a block inside its stile, a late on the outside thereof, screws which c amp the plate and block with the metal sheet of the stile therebetween, and a pivot bolt which extends from the window-frame into the block.

3. A sheet-metal Window, ,having a pivotholt projecting from its frame into the Sashstile, a block in the stile, into which the bolt extends, said stile having a vertical slotinits face, beside the block, and fastening devices extending through the slot and securing the block at adjustment in the stille.

Inutestimony whereof I have signed my nalne to this specification in the presence of two subscribing witnesses.
